Cleaning old quilt
I received an old quilt top from a neighbor who would like me to try to finish it. It was made by her mother who died when my neighbor was about two and she's 83 now. It has been in a storage shed for the last 25 plus years and desperately needs some cleaning. Some of it has yellowed from age but the red fabric in it is still very vibrant. I know that I don't want to put it in the washing machine but will probably gently wash it in the bathtub. My question is, what type of cleanser should I use. I know there are different kinds out there but need some input on what some of you have used. Thank you for any help you can give me.
